Basic

Safety

Precautions

Burn

Protection.

Molten

metal,

sparks,

slag,

and hot

work

surfaces

are produced

by welding,

cutting,

and allied

processes.

These can

cause

bums

if precautionary

measures

are

not used.

Workers

should

wear protective

clothing

made

of fire-res istant material. pant cuffs, open pock-

ets,

or

other places

on clothing

that can

catch

Electrical

Hazards.

Electuic

shock

can

kill.

However,

t can

be

avoided.

Live

electdcal

should

be gounded.

The

is

not a

lead.

It

is used

only

to

A sepamte

is

requlred

to ground

The

work-

should

lrot

be

mistaken

for

a

Fumes

and

Gases.

Many

welding,

cutting,

and

allied

processes

produce

furnes

and

which

may

Avoid
